Lost internet due to windows?

Hey I have a Acer windows vista home premium PC. Had it for about 10 years.

2 days ago I was loading stuff onto a usb stick and my Mcafee (not subscribed) popped up warning me of something, was in bit of rush so didn't read it and just clicked to get rid of about 5/6 things.

My internet went. The connection generally is okay as it works with my tablet and phone.

When switch PC on, the welcome thing takes longer and then the screen goes blank blue for about 30 seconds then the main desktop screen appears as per normally. Then a box appears bottom right saying, "Failed to connect to a windows service. Windows could not connect to the system event notification service service. As administrator, you can review the system event log for details about why the service didn't respond." When I click to diagnose and repair connection, it fails to repair the DHCP client service. No matter what I try to repair nothing works. I did a system restore, never had a problem with doing many of them in past, this one just wouldn't work. I've done various command prompts and hkey local stuff, nothing. Looked in mcafee but nothing.

My local area connection is enabled
IPv4 Connectivity - Not connected
IPv6 connectivity - Not connected
Media state Enabled
Duration 36mins
Speed 1.0Gbps
Under the details tab, DNCP Enabled - Yes

Quite happy to buy a new PC, but would be equally nice to fix these damn things as I like defying Microsoft charging for windows 10 lol

Thanks for any and all help!

Did you try?

Safe Mode with Networking?

This should disable blocks put in by apps like McAfee.

Re: McAfee

What exactly is "McAfee (not subscribed)"?

Good question.

I've seen machines with such apps block the internet if they expire. "For your safety."

Hey guys, thanks for showing an interest, 2 other forums didn't.

I found this on another
Start computer in safe mode.
logon on to administrator.
Click the start button
Search "cmd.exe"
Select it and then "ctrl - shift - enter" to allow elevation request
Type in - "netsh winsock reset" press enter
Then Restart your computer
It worked !!
And it did for me.
